Most likely not. Contrary to what was being said, 40 hours is still very much the norm in The Netherlands. Some people choose to work less (36 or 32 hours is common), but that obviously also means less income.
Although a strong indicator, this does not necessarily imply an SQLi. If the variable is sanitized before the query (for instance, the variable is cast to an int), there is no SQLi to exploit.
So it's very possible that these graphs are riddled with false positives.
Although I agree with you that this does not seem like a good reason to renounce your US citizenship over, it is pointing out some issues with the US tax code that need fixing.

As I'm responsible for a small development department, I regularly do interviews including written tests. If one of the candidates would ask me if they could do it on their notebook, I would probably say no, as it sort of defeats the purpose.

Being from The Netherlands myself, this is simply not true. Euthanasia is something that both the patient (and if the patient is no longer capable of deciding for himself, his family) and the doctor have to agree on.
Stopping treatment or prescribing drugs that will shorten the patient's life is also being done in the US, so if you want to inflate the suicide numbers, you have to do it for all.
